Could anyone please help me, I need a code which after the press of a button inputs certain IP Addresses in the Hosts file.

Please help,

Thanks In advance

I can't seem to edit my post so im just going to add this one.

What I really what to do is the hosts file located in C:\windows\system32\drivers\etc\hosts, which is used to map hostnames to ip addresses,I need to input data or a line.
eg: # 123.412.423:232 ww.sdwxc.com
into it, i can only input data when it is in .txt format but the hosts file is in someother format.

What I really need is when i click a button on a program I add a line into the hosts file to block a particular site,but after its done it should be back to its original format.

i 'vce no idea what you are trying to do
but you can always open any kind of file in to a text stream using the
my.computer.readAlltext()
function
but i muz say that theres a chance of havng gibberish instead what you want
after you do your changes use
my.computer.writeAllext()

yes u can do this,just open host file in append mode as text file nd write in it what u want to, before sometimes i did it to make a simple virus.if u do nt able to do this then tell me i will write full code here
